Copy U-Boot to STAGING_DIR_IMAGE (and append it to the EVA-image from
there) to fix image generation using the image-builder.
Also remove the bootloader from DEVICE_PACKAGES and instead use the
BUILD_DEVICES directive from within the U-Boot makefile.
This fixes eva-image generation using the OpenWRT image-builder.

(cherry picked from commit 634c733065)
When we provide the HOSTCFLAGS to the U-Boot build it will fail because
it can not find the u-boot provided header files any more.
Just overwrite and not append the package specific configuration on top
of the configuration provided by u-boot.mk.
uboot-fritz4040 is based on U-Boot 2012.07 and this problem is probably
similar to the problem seen with the lantiq and ar71xx u-boot build.
